===Early childhood===
===Early childhood===
Swapan Chattopadhyay was born in [[Calcutta]], [[India]], and spent his early childhood years in the [[Himalayas|Himalayan]] hill town of [[Darjeeling]]. The Indo-China conflict over the disputed territory of Tibet led the family to relocated to the metropolitan mega-city of Calcutta in the early 1960s, where he received high school and university education. He was awarded a high school diploma in 1967 as a National Scholar, graduating from [[Ballygunge Government High school|Ballygunge Government High School]] and was selected a National Science Talent Scholar in a nationwide competition. It was in this high school, that he was the beneficiary of the gifted mentorship of the school's physics teacher, Pramatha Nath Patra.
Swapan Chattopadhyay was born in [[Calcutta]], [[India]] and spent his impressionable early childhood years in the [[Himalayas|Himalayan]] hill town of [[Darjeeling]]. His father, educated as a chemist but trained in telecommunications via his chosen profession, was posted, from the mid 1950s till the early 1960s, in Darjeeling as the “officer-in-charge” of communications in the mountain districts of Darjeeling, [[Sikkim]], parts of [[Bhutan]], [[Nepal]] and [[Tibet]] (now [[China]]) on behalf of the Post, Telegraph and Telephone (PT&T) department of India. There growing up as a young boy, along with developing an appreciation for the region’s famously exotic tea gardens and five-mile high mountain peaks, he was fascinated with spotting the [[Sputnik]] in the sky and was also one of a half dozen fortunate children who were offered hand-held mountaineering lessons by [[Sir Edmund Hillary]] and [[Tenzing Norgay]], upon inauguration of the pioneering [[Himalayan Mountaineering Institute]] by the governments of India and [[New Zealand]] in 1957. This started his lifelong fascination with science on the one hand and climbing mountains and trekking on the other, in addition to an addiction for tea. At one point in his formative years, he had seriously considered the profession of mountain climbing and much later in life, has been driven to explore the remote regions of western Tibet, the sources of the rivers [[Indus]] and [[Brahmaputra]], the sacred mountain [[Kailas]] and [[lake Manasarovar]].
The Indo-China conflict over the disputed territory of Tibet and subsequent flight of [[Dalai Lama]] from Tibet into India brought serious conflicts in the mountain region, putting considerable stress in the civilian population. He relocated with family to the metropolitan mega-city of Calcutta in the early 1960s, where he received high school and university education. He was awarded a high school diploma in 1967 as a National Scholar, graduating from [[Ballygunge Government High school|Ballygunge Government High School]] and was selected a National Science Talent Scholar in a nationwide competition. The high school had also previously graduated the internationally acclaimed Bengali film director [[Satyajit Ray]], who along with another contemporary Bengali radical film director [[Ritwik Ghatak]], had considerable influence on his young mind. It was in this high school, that he was the beneficiary of the gifted mentorship of the school’s legendary physics teacher, Pramatha Nath Patra.


===Higher education and early career===
===Higher education and early career===
Chattopadhyay completed his [[Bachelor of Science|B.Sc]]. degree from [[Calcutta University]] in 1970, with Honors in [[Physics]], graduating from [[St. Xavier’s College]], a well known institution run by the early [[Jesuit]] clergy in India, which also boasts of having graduated the famous Indian scientist [[Jagadish Chandra Bose|Prof. Jagadish Chandra Bose]] and Indian steel tycoon [[Laxmi Mittal]]. Caught in the turmoil of the politically vibrant and active university community in the city of Calcutta in the state of West Bengal in the late 1960s and early 1970s, he circumvented a delayed prospect of admission into the university’s post-graduate program by joining the [[Indian Institute of Technology]] at [[Kharagpur]], eighty miles south-west of Calcutta, for his post-graduate studies, completing his M.Sc. degree with specialization in [[Particle Physics]] in 1972.
Chattopadhyay completed his [[Bachelor of Science|B.Sc]]. degree from [[Calcutta University]] in 1970 in [[physics]]. He continued his studies at the [[Indian Institute of Technology]] at [[Kharagpur]], for his post-graduate studies, completing his M.Sc. degree with specialization in [[Particle Physics]] in 1972.


Hoping to combine his passion for physics with the desire to explore nature, and upon direct invitation from Prof. Michael Moravscik as Chair of the Physics Interview Committee of the American Physical Society, he then joined in 1972 the Physics department of the University of Oregon at Eugene in the Pacific Northwest region of USA, known for its rugged natural beauty. However, over time, the draw towards the larger, diverse and vibrant campus of the University of California at Berkeley got stronger and with direct support and recommendation from Prof. Rudy Hwa and Prof. Berndt Crasemann while working on research projects with them in the summers of 1973 and 1974, he joined the University of California at Berkeley in 1974, as a Ph.D. student in the Department of Physics. After flirting for two years (1974–1976) with the inimitable Berkeley brand of theoretical particle physics, then known as the “[[S-matrix]]” and “[[Bootstrap model|Bootstrap]]” theories of “[[strong interactions]]”, under tutelage of [[Geoffrey Chew|Prof. Geoffrey Chew]], Chattopadhyay was attracted away by the eclectic and pragmatic charm of accelerator physics dealing with charged particle and light beams under mentorship of some of the most prominent accelerator pioneers in the original accelerator laboratory created by [[Ernest Orlando Lawrence]] at Berkeley, such as: [[Edward J. Lofgren]], [[Andrew Sessler]], Denis Keefe, L. Jackson Laslett and Glen Lambertson, to name a few. In 1978, he was also heavily influenced by the visit of [[Simon van der Meer]] and [[Carlo Rubbia]] to the laboratory, speaking on the possibilities of [[stochastic cooling|stochastic phase space cooling]] of [[antiproton]] beams and the exciting possibilities with proton-antiproton collisions. He was also simultaneously being encouraged by [[Owen Chamberlain|Prof. Owen Chamberlain]], discoverer of the ‘antiproton’ and a Berkeley Nobel laureate, to engage in antiproton beam research. He subsequently completed his PhD dissertation on the timely and critical topic of stochastic cooling of bunched beams of antiproton from the University of California (Berkeley) Physics department in 1982 and continued onto CERN as an “attaché scientifique” in the Super Proton Antiproton Synchrotron working with Daniel Boussard, Simon van der Meer and Carlo Rubbia, contributing to the ongoing program of stochastic cooling of antiproton beams, which led to the discovery of the [[W boson|W]] and [[Z boson|Z]] vector bosons at CERN, and to the early ideas of stochastic cooling of “bunched” beams, which today are being applied successfully to [[phase space]] cooling of heavy [[ions]] at the [[Relativistic Heavy Ion Collider]] at Brookhaven National Laboratory, leading to exciting new investigations of the [[Quark Gluon Plasma|‘quark-gluon’ plasma]] in gold-on-gold collisions.

However, over time, the draw towards the University of California at Berkeley got stronger and he joined the [[University of California, Berkeley|University of California at Berkeley]] in 1974, as a [[Doctor of Philosophy|Ph.D.]] student in the Department of Physics.

Chattopadhyay returned to Lawrence Berkeley National Laboratory in 1984, where he led and defined the accelerator physics of the [[Advanced Light Source]] (ALS) and contributed to the conceptual design of the [[Superconducting Super Collider]] (SSC), pioneered the accelerator physics which underpinned the Berkeley-Stanford asymmetric B-factory (PEP-II) for [[CP-violation]] studies, and initiated the Berkeley FEL/Femtosecond X-ray Source and [[Plasma acceleration|Laser-Plasma Acceleration]] development. He was a Senior Scientist, a [[Visiting Scholar|Guest Professor]], and the Founder/Director of the Center for Beam Physics at Berkeley, until his move to Thomas Jefferson National Accelerator Facility in 2001 as the Associate Laboratory Director for Accelerators, after 25 years at the University of California and Lawrence Berkeley National Lab.
At Thomas Jefferson National Accelerator Facility, he made critical advancements in microwave superconducting linear accelerators leading the way to current and future grand instruments of science such as the high precision CEBAF and its 12 GeV upgrade for precision research in [[hadron]]ic physics, [[Spallation Neutron Source]] at Oak Ridge National Laboratory, USA to advance [[neutron]] sciences and novel materials research, and the current [[superconducting]] version of the [[International Linear Collider]], to name a few.
His research at the Cockcroft Institute in UK included development of sources of “ultra-cold” [[Relativistic electron beam|relativistic free electron beams]] to advance coherent [[electron diffraction]] techniques; production of novel coherent and ultra-short pulses of [[photons]] (e.g. x-ray FELs); novel acceleration methods; investigation of [[photonic crystals]] and [[metamaterial]] structures for charged particle acceleration; novel high energy colliders; cavity search for “dark matter” and laboratory investigation of “[[dark energy]]” via [[atom interferometer]] techniques. Chattopadhyay is currently working for [[Fermilab]] and [[Northern Illinois University]] (NIU) acting as a distinctive professor and director of accelerator research.<ref>{{cite journal|title=Faces and places: Chattopadhyay returns to new challenges in the US|journal=CERN Courier|date=February 2014|volume=54|issue=7|page=32|url=http://iopp.fileburst.com/ccr/archive/CERNCourier2014Sep-digitaledition.pdf}}</ref>

Swapan Chattopadhyay CorrFRSE (born December 26, 1951) is an Indian American physicist. Chattopadhyay completed his PhD from the University of California (Berkeley) in 1982.[1]

Currently, Chattopadhyay is part-time Faculty at University of California at Berkeley, adjunct professor of photon science at SLAC, Stanford University, and emeritus president's professor at Northern Illinois University (NIU) and distinguished scientist emeritus at Fermi National Accelerator Laboratory (Fermilab), where he was a member of the director's senior leadership team and was director of the Cooperative Research and Development Agreement between Fermilab and NIU.[2][3]

Chattopadhyay is a Fellow of the American Physical Society,[4] American Association for the Advancement of Science,[5] Institute of Physics (UK), Royal Society of Arts, Manufactures and Commerce (UK) and Corresponding Fellow of the Royal Society of Edinburgh[6] and a member of many international panels and committees, including the "International Committee for Future Accelerators" and the DESY Science Council (2008–2013).[7][8]

Early life and education

[edit]

Early childhood

[edit]

Swapan Chattopadhyay was born in Calcutta, India, and spent his early childhood years in the Himalayan hill town of Darjeeling. The Indo-China conflict over the disputed territory of Tibet led the family to relocated to the metropolitan mega-city of Calcutta in the early 1960s, where he received high school and university education. He was awarded a high school diploma in 1967 as a National Scholar, graduating from Ballygunge Government High School and was selected a National Science Talent Scholar in a nationwide competition. It was in this high school, that he was the beneficiary of the gifted mentorship of the school's physics teacher, Pramatha Nath Patra.

Higher education and early career

[edit]

Chattopadhyay completed his B.Sc. degree from Calcutta University in 1970 in physics. He continued his studies at the Indian Institute of Technology at Kharagpur, for his post-graduate studies, completing his M.Sc. degree with specialization in Particle Physics in 1972.

Chattopadhyay then joined in 1972 the Physics department of the University of Oregon. However, over time, the draw towards the University of California at Berkeley got stronger and he joined the University of California at Berkeley in 1974, as a Ph.D. student in the Department of Physics. After flirting for two years (1974–1976) with the inimitable Berkeley brand of theoretical particle physics, then known as the "S-matrix" and "Bootstrap" theories of "strong interactions", under tutelage of Prof. Geoffrey Chew, Chattopadhyay was attracted away by accelerator physics dealing with charged particle and light beams. After having completed his PhD, he moved to CERN as an "attaché scientifique" in the Super Proton-Antiproton Synchrotron, contributing to program of stochastic cooling of antiproton beams.[9]

Career

[edit]

Chattopadhyay is noted for his pioneering contributions of innovative concepts, techniques and developments in high energy particle colliders, coherent and incoherent light sources, ultrafast sciences in the femto- and atto- second regimes, superconducting linear accelerators and various applications of interaction of particle and light beams.[10][11] He has directly contributed to the development of many accelerators around the world, e.g. the Super Proton-Antiproton Synchrotron at CERN,[9] the Advanced Light Source at Berkeley,[12] the asymmetric-energy electron-positron collider PEP-II at Stanford,[13] the Continuous Electron Beam Accelerator facility (CEBAF) at Jefferson Lab and the Free-Electron Lasers at Jefferson and Daresbury Laboratories.[14]

He was formerly the Sir John Cockcroft Chair of Physics jointly at the Universities of Liverpool, Manchester and Lancaster—the First Chair of accelerator physics in UK, named after the British Nobel Laureate credited with creating the field.[15][11] In this role he was the Inaugural Director of the Cockcroft Institute (UK), having been appointed in April 2007. Prior to this he served as associate director of Thomas Jefferson National Accelerator Facility (2001–2007),[16] staff/senior scientist and founding director of the Centre for Beam Physics at Lawrence Berkeley National Laboratory (1984–2001); and scientific attaché at CERN (1982–1984).[17]

After the period spent at CERN, Chattopadhyay returned to Lawrence Berkeley National Laboratory in 1984, where he led and defined the accelerator physics of the Advanced Light Source (ALS)[12] and contributed to the conceptual design of the Superconducting Super Collider (SSC),[18] pioneered the accelerator physics which underpinned the Berkeley-Stanford asymmetric B-factory (PEP-II) for CP-violation studies, and initiated the Berkeley FEL/Femtosecond X-ray Source and Laser-Plasma Acceleration development. He was a senior scientist, a guest professor, and the founder/director of the Center for Beam Physics at Berkeley,[19] until his move to Thomas Jefferson National Accelerator Facility in 2001 as the associate laboratory director for accelerators. At Thomas Jefferson National Accelerator Facility, he made critical advancements in microwave superconducting linear accelerators leading the way to current and future grand instruments of science such as the high precision CEBAF and its 12 GeV upgrade for precision research in hadronic physics,[20] Spallation Neutron Source at Oak Ridge National Laboratory, USA to advance neutron sciences and novel materials research, and the current superconducting version of the International Linear Collider, to name a few. His research at the Cockcroft Institute in UK included development of sources of "ultra-cold" relativistic free electron beams to advance coherent electron diffraction techniques; production of novel coherent and ultra-short pulses of photons (e.g. x-ray FELs); novel acceleration methods; investigation of photonic crystals and metamaterial structures for charged particle acceleration; novel high energy colliders.

While working for Fermilab and Northern Illinois University he contributed to cavity searches for dark matter; investigation of ultra-light dark matter and dark energy via atom interferometry, and the creation of the Matter-wave Atomic Gradiometer Interferometric Sensor (MAGIS-100) experiment.[21][22] Having contributed to the conception, design, construction, commissioning and operation of numerous accelerators for particle and nuclear physics, photon and neutron sciences around the world, with significant research accomplishments in advanced particle and photon beam physics,[23][24] and mentoring scientists around the world, in the developing nations in particular, in accelerator developments as a unifying global force among nations, Swapan Chattopadhyay is a frequently invited speaker and advisor at professional societies and government research agencies, serving on numerous editorial, advisory and review committees throughout the world.

He served as the Vice-Chair, Chair-elect, Chair and Past-Chair of the American Physical Society's Division of Physics of Beams (2007–2011). Chattopadhyay has delivered lectures throughout the world e.g. Saha Memorial Lecture,[25] Homi Bhabha Lecture, Raja Ramanna Memorial Lecture, and Cavendish Lecture among many.
